diastereoisomeric

Two diastereoisomeric forms, respectively SS and RR, of chemically modified channels in which a dioxolane ring links the formylated N-termini of two gramicidin monomers, were shown to form ion channels.

Whilst most of the discussion has been about diastereoisomeric salts, it does not have to be so.

Both 9 and 10 have four stereogenic centers giving rise to diastereoisomeric compounds existing as mixtures of two racemates.
